An awesome combination commonly used by the more experienced guys in the game.
What you do: Throw a really fast 1-2 to keep the guy on the defensive and then a big left hook. (REMEMBER: You have to throw a really fast 1-2 with no emphasis on power – pure focus on speed. The cross is thrown slightly after the jab so that the 1-2 lands right after one another which is then followed by a big left hook that is thrown with all your power.)
Why it works: Basically, the cross will come so fast that it will disturb your opponent who is not expecting the punches to come so fast that the left hook will surprise him. In some occasions, the cross might land which makes the opponent instinctively put his glove in front of his face to block punches from hitting… which then leaves him open for the big hook. You are also welcome to try 1-2, PAUSE, and THEN the big hook. FAST 1-2, BIG Left hook!
